Linear entity responsible for the risk of the Flood Risk Prevention Plan (PPRI) of the Fecht Versant Basin in the Haut-Rhin

The origin of the risk characterises the real-world entity which, through its presence, represents a potential risk. This origin may be characterised by a name and, in some cases, a geographical object locating the actual entity causing the risk. The location of the entity and the knowledge of the dangerous phenomenon are used to define the risk pools, the risk-exposed areas that underpin the RPP. For NRPPs, this entity may, for example, correspond to a watercourse, a geologically unstable area.风险源头（risk origin）指一类现实世界实体，其存在本身即构成潜在风险。该风险源头可通过名称进行表征，在部分场景下，还可通过用于定位该风险致因实体的地理对象来补充描述。实体的位置与危险现象的相关知识，可用于定义风险池（risk pools）——即支撑RPP的风险暴露区域（risk-exposed areas）。 针对NRPPs，该实体例如可对应为河道或地质不稳定区域。
